The place where I was getting hung up was how to get the data that was captured in the Imagick::getImagePixelColor operation into an ImagickPixel object. I was trying to find ways of passing the value to a newly instantiated ImagickPixel object. Well, it appears that once you've captured your color data using Imagick::getImagePixelColor, what's returned IS an ImagickPixel object!

As a further note, you do not need to convert this to a human readable format if you just want to take a color sample at a single point on your image to plug into another operation.

For example, if you wanted to perform a flood fill effect on a certain color you could plug in the instance of the ImagickPixel object directly.

The following fill perform a flood fill effect at coordinates 1,1 on your image using Green as the fill color and the color sampled at 1,1 as the target color to fill.
